let N be a positive interger less than 10^2002. when the digit 1 is
placed after the last digit of N, the number formed is three times the
number formed when the digit 1 is placed infront of N. How many
different values of N are there???
but it's even harder without a calculator...i had to do this for a maths
challenge in school, without a calculator-argh!!!
